Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25818, here are decompositions:
- 17 + 25801 = 25818
- 19 + 25799 = 25818
- 47 + 25771 = 25818
- 59 + 25759 = 25818
- 71 + 25747 = 25818
- 101 + 25717 = 25818
- 139 + 25679 = 25818
- 151 + 25667 = 25818
Showing the first eight; more decompositions exist.
